The cloth bag dust removal device according to claim 1, wherein the top of the filtering partition plate (4) is fixedly connected with uniformly distributed annular nut seats (27) which are sleeved outside the opening, the outer side wall of each annular nut seat (27) is provided with a threaded portion, each threaded portion is in threaded connection with a screw tube (28), and the bottom of the cloth bag (7) is fixedly connected between the threaded portion and the screw tube (28).
6. The cloth bag dust removal device according to claim 1, wherein the rotating rod (9) and the ash removal rod (10) are both hollow structures, and the outer side wall of the ash removal rod (10) is provided with a bristle layer.
7. The cloth bag dust removal device according to claim 1, wherein the sealing ring on the second metal mesh (6) is fixedly connected with the sealing ring on the cloth bag (7).
8. Use of a bag house dust removal device according to claim 3, characterised by the steps of:
s1: firstly, an electric valve (13) at an ash cleaning opening is closed, dust-containing gas is sent into a lower chamber of a case (1) through an air inlet, the dust-containing gas passes through an opening on a filtering partition plate (4) and sequentially passes through a first metal mesh (5), a cloth bag (7) and a second metal mesh (6), and the filtered gas enters an upper chamber in the case (1);
s2: the gas in the upper cavity is sent into the lower cavity of the filter box (23) through the exhaust pipe (11), the gas entering the filter box (23) flows in the gap between the adsorption plates (24), then flows into the upper cavity of the filter box (23) to complete secondary filtration, and then is discharged through the gas outlet pipe (12);
s3: the gas after secondary filtration is sent into the gas storage cylinder (15) through the snake skin metal hose (20), the gas sent is increased continuously, the piston plate (16) pulls the tension spring (18) to slide in the gas storage cylinder (15), when the gas slides, the piston rod (17) is driven to extend, in the extension process, the turntable (19) is driven to rotate, the torsion spring (22) is driven to tighten up in the rotation process of the turntable (19), when the gas is extended to the farthest point, the piston plate (16) slides to the gas outlet end of the gas storage cylinder (15), the high-pressure gas in the gas storage cylinder (15) is sent to the outside of the case (1) through the gas outlet hose (21), at the moment, the pressure in the gas storage cylinder (15) is reduced, the tension spring (18) rebounds under the action of the rebounding force, meanwhile, the torsion spring (22) rebounds to drive the turntable (19) to do reciprocating motion, and further drive the transmission rod (8) and the first metal mesh (5) to do reciprocating motion, when the first metal net (5) does reciprocating motion, the ash removing rod (10) is matched with meshes on the second metal net (6) to do circular motion along the rotating rod (9), so that dust on the inner wall of the cloth bag (7) is cleaned and falls into an ash removing opening;
s4: the electric valve (13) is opened, the deposited dust at the dust removing port falls into the deposited dust frame (26), and then the electric valve (13) is closed to disassemble the deposited dust frame (26) filled with the deposited dust for centralized treatment.
